Nest Bedding's Supportiveness

A supportive mattress is the key to waking refreshed. You want something that will align your spine rather than causing you nightly pain. These mattresses provide the kind of support that works with your body.

Edge SupportFor those that like sitting on the side of the mattress, edge support is very important. These mattresses offer competitive edge support and prop up sleepers along the side.

Bowling Ball & Density TestsPopular among readers, the bowling ball test gives a good reading on mattress firmness and evenness of support. If a mattress is unneven in its supportiveness, then there is a big problem. Luckily, these mattresses offer good support across the mattress surface.

Nest Bedding's Durability

Durability is the single most important criteria for buying a new mattress next to initial comfort. In this day and age, mattresses should last between 7 and 12 years with average use to be considered durable. That said, mattress craftsmanship and sleeper body weight can affect durability as well. These mattresses do a great job with durability overall. There are some heavier folks that may experience a decrease in longevity.

Sleep Science's Owner Satisfaction

Each of us need to read up on what customers are saying before we buy a product worth hundreds or thousands of dollars. That said, it can be a more difficult prospect when browsing countless brands and other sites. We examined the online reviews and sentiment and found that customers give these mattresses above average marks overall. However, there is some mixed feedback Make sure to study the specifications to make sure one of these mattresses will work for you.

Sleep Science's Supportiveness

Experts agree that a supportive mattress is very important for having a good night's sleep. These mattresses are generally rated well at the beginning, but some folks had complaints about the supportiveness over a long duration. Make sure to take a look at the reviews to make sure these mattresses work for you.

Edge SupportEdge support is important to most folks and makes it easy to get in and out of bed. These mattresses provide okay edge support, but some sleepers may experience more dipping over time.

Bowling Ball & Density TestsIn density tests that measure the initial supportiveness, support is initially even throughout the mattress. Some folks, however, have described issues with support degrading over time.

Sleep Science's Durability

Finding a mattress that has comfort that lasts can save you lots of money. But, these days, everything from what you wear to where you sleep are degrading faster. Customers give mixed ratings when it comes to the longevity of these mattresses. Each person is affected differently by their mattress and these may be fine for you, but others have had complaints long term. Do some additional research and make sure that your choice should work well for you before purchasing.

Best Night’s Sleep - Michele S.

King Alexander Series - Cam Z.

Purchased this bed a couple weeks ago and wanted to give it some time to make sure before I wrote a review. This Bed is Fantastic! I did so so so much research and reading of reviews on beds to make sure I picked the right one. I'm still trying to figure out what some of the two star reviews are talking about. I'm almost mad they made me so nervous about purchasing the bed. I purchased the King in medium firmness and it is so comfortable....to the point that I was late for work one day which never happens! Keep in mind, my last bed was an old spring one with a memory foam topper. I think what really sold me was the customer service. The people that I talked to on the live chat were super awesome. I spent 10 minutes talking to one guy about my body weight and trying to decide which level firmness I should go with. Another company I was leaning toward was more expensive and didn't have any Black Friday deals. This wasn't a problem but the way they told me was. They went on about how they are a true mattress company unlike these "phony" other ones and that's why they don't give deals.... and you had to pay 100 bucks for delivery. anyway the customer service was fantastic and in my opinion that wins out every time, especially when it comes to returning something. In conclusion, mattress is great, I'm hoping to be able to get their pillows some day.

Very comfortable bed but sleeps hot - Dan S.

I wrote a review before for the Alexander signature bed, but it did not get posted. It was either too long or nest bedding didn't like what I said. I ordered the bed in the king size and medium firmness. At first the medium felt very hard and I had to check the tag on the bed to confirm it was medium. After a few weeks the bed softens up very nicely. Overall the alexander signature is extremely supportive and provided great pressure relief. the main issue my wife and I had was the bed slept very hot. We purchased a foundation from nest that was breathable (we were using new tempurpedic flat foundations). We also purchased bamboo sheets, wool comforter and linen duvet cover and four different bed protectors (two waterproof and cooling and two non-waterproof and cotton). Using the organic cotton bed protector the bed was cool enough to sleep on on most days. Ultimately we returned the bed for the hybrid latex. The bed would be a 5 star product if it slept cooler.

Overall a good bed - Anne W.

I returned my signature hybrid bed for the signature series "medium" because the hybrid did not feel enough like memory foam for me. The new mattress feels much more like a memory foam bed but maybe not quite to the level I was hoping. The mattress does sleep bit warm but overall comfortable. Customer service has been great.

Great bed and really helps - Ahmed M.

Great bed and really helps with my back problems

Incredible support/ pressure relief - Dan S.

I purchased the signature series medium firmness in the king size. I had very high hopes for this bed. I purchased a $2k bed from Denver Mattress about 1.5 yrs ago and have suffered from back pain the entire time. The Alexander arrived from FedEX (dumped in my driveway. Not nest bedding fault, but a lazy fedex driver). When I opened the box there was minimal offgasing, which went away quickly. I originally put the Alexander on a solid tempurpedic foundation. The bed at first felt much firmer then a medium. So much so that my wife wanted me to send the bed back after one day. After about a week the bed softened up very nicely and is a true medium. After the bed broke in a bit it was with out a doubt the most comfortable bed I've every slept in. The only problem was, my wife and I were waking up every night extremely hot. We were both so hot that it was hard to sleep. We tried two different cooling waterproof bed protectors, and a regular pillow-top non-waterproof cotton protector and bamboo sheets. The cooling protectors made the bed sleep hotter. I then purchased an organic stretch knit cotton protector (non-waterproof), the nestbedding foundation (which is very breathable) and the bed did sleep cooler (although I spent hundreds of dollars at this point). By this time I had already ordered the latex hybrid bed from nest to replace the signature bed. Ultimately, I highly recommend the Alexander signature bed to anyone looking for amazing support and an amazing feeling bed. However, if you sleep very hot you might want to look at the hybrid or latex beds. Also, nest beding was very easy to work with on the replacement. They had me donate the Alexander signature bed. I was able to find a very deserving couple that was sleeping on a 30 yr old mattress that are beyond happy they received this bed. Customer service was excellent from Nestbedding. If the bed slept cooler it would be a 5 star review.

The best mattress I've ever - Christy C.

The best mattress I've ever purchased!!!

Super comfy mattress!!! - Charlie T.

Really liking this mattress, it's been great to sleep on. So much support and nice and thick. It definitely still smells like memory foam though even after having it for more than a month. I let it air out for a couple of days before using and can still smell it. This varies from mattress to mattress I'm sure but just be aware it can happen.

Alexander bed - William K.

Happy but at the moment having trouble with my shoulders hurting maybe needs to be softer. Contemplating ordering a king size if I can correct the shoulder ache

Love this bed... - Ronald M.

Bought this mattress because our $3500 Tempurpedic became senile and lost its memory after only eight years. This Alexander Signature series mattress has been great right out of the box. We have been sleeping on it now for about 6 weeks and NO complaints. We highly recommend this mattress & company. Fast , friendly, knowledgeable service.

Great bed - Laura F.

Extremely Comfortable - Andy S.

We have recently purchased the Alexander Signature series bed, and holy cow, I noticed a difference in sleep within the first week. I felt more rested, and it was sure comfy. It was really easy to take out of a box and move from the apartment building mail office to our apartment. The box ripped while we were carrying it, but it almost made it easier to grip the round mattress than the handles on the box. I would definitely recommend this mattress and nest bedding to whoever is talking about buying a new mattress. We also were able to try it out at an online mattress showroom we have in the Twin Cities called Sleep Sherpa. So if you are not from Minnesota, look up to see if there are any of those type stores by you!

Nest, Alexander series - Stephanie S.

Shipped quickly and neatly. Love the mattress, it needs a little time to mold into a custom fit the sleeper, and now after the adjustment period, I am finding more peaceful and restful sleeps. Love the financing tool as well! Super quick and easy.

Love the Alexander (soft) ! - Jason B.

This was our 2nd purchase from Nest for our guest bedroom. We love the Alexander soft and the service Nest also provides. Thank you!

No regrets with purchase - Brian H.

Excellent. Well built/designed and no damage/flaws. I really am happy with this purchase, sleeping has improved and this is extremely comfortable. Sleepopolis was a fantastic resource for study. I chose this over five others. Very difficult decision, but again, I have no regrets.

Love our new mattress - Michelle R.

Excellent customer service throughout the order process and all arrived as expected and on time. Bed is super comfy!

Favorite Memory Foam Matress - James s.

I’ll start by saying that I prefer a spring matress over memory foam but for a foam matress this is far and away my favorite I have slept on. Tried another brand and returned it as it was too firm for my preferences.

Signature Hybrid medium - Jon

So soft. A guy my size, 230 5'9'' sink right in. Great on wife's shoulders as a side sleeper. I myself prefer a bit more firm but highly recommend this mattress and Nest bedding for that matter. Great customer service and great communication.

Love it. A great nights - Meredith S.

Love it. A great nights sleep.

Great bed - Katie A.

We have had the signature medium for about a month, king size. When we first got it, it was really firm, I couldn’t even sleep on it. But, it has softened up a bit, but no much. I have to say that I have since gotten used to it, and I actually find it very comfortable. I am used to sleeping on a pillow top soft mattress, so the transition was difficult, but worth it in the end. I sleep more soundly, and my arms don’t fall asleep anymore. I am a side sleeper, and no more back and hip pain. I do however, wish it was just slightly softer. If you are looking for a softer matress and are stuck between the soft and medium, the medium to me is slightly on the firmer side. I am 5’7”, about 140 lbs. my husband is around 200, but he can sleep on anything. Overall great mattress.

Alexander King Soft - Rachel B.

I was hesitant to try buying a mattress online. I'm glad I did and I wish I hadn't waited so long. This mattress is not as soft as our last one but after sleeping on it a few nights, I realized that it is more supportive but still soft enough to snuggle into. Our previous mattress (from a retail store) in retrospect was too soft, didn't give enough support and was twice as expensive. This is a much better buy. My husband and I both love the new mattress. I'm glad I didn't go with the medium, it wouldn't have been plush enough for me. This feels more like a medium soft mattress. It was easy to set up. It's been over a month now and so far so great!

Firm Support on Par With Tempur-Pedic - Bob H.

I own a king Tempur-Pedic Contor firm, spent $USD 3300 several years ago and my wife and I really love it. The Nest Alexander firm king we purchased two months ago is absolutely fully comparable to it in terms of comfort and full body support at one third the price. Excellent value for the money, we cannot distingush any differences between the two mattresses.

Nest alexander signature medium - Karen R

We had a spring mattress prior, never had memory foam. When needed, and overdue for, a new mattress, spent much time looking at mattresses and reading reviews. We got our mattress from Nest almost 4 wks ago. I like a softer mattress then my husband so compromised with a medium of the alexander signature mattress. Husband noticed a little outgassing, but I didn't (i do use 2 pillows). I did not feel there was any breaking in time, mattress was comfortable right away. Both of us are comfortable with this mattress although not sure it helps with my husbands back pain. I have a problem with hot feet so i was interested in the cooling of the mattress. The bed warms up under your body torso but elsewhere is cool. That helps me because i can move my feet and it is cool anywhere they are. There is some collapse at bed edge but has not been a problem and I do sit on edge to put socks and shoes on. It is difficult making bed, may be because set in platform bed and diff to get sheets around corners and edge- too heavy to lift corners up.

Great value and workmanship - John B.

Was skeptical, but now a believer. Great night sleep.

Great customer service - Brad R.

Very comfortable mattress, but their customer service is what makes this company stand out. Excellent.

Great product, so comfy! - Kirk W.

I purchased the Alexandar signature series and I couldn't be happier with my purchase! One month in and it's as comfortable as ever! It's hard to want to get up in the morning...

More Than We Dreamed - Jefferson M.

I cannot find the words to express our satisfaction with The Alexander Signature Series Mattress. It is the best mattress we’ve ever owned. Period. Back problems gone. Pressure point pains gone. Stiff joins in the morning gone. A perfect night’s sleep every night since it arrived. We could not be more pleased!

The firm is REALLY FIRM - Zach J.Store Owner

I'm in the process of contancting the company to try to change my mattress for the medium firm because the signature firm is almost like sleeping on the ground imo. I've had it for a month and a half and I've tried jumping on it and tried to break it in but it feels really hard. I'd go for the medium at least. 3 stars for positive customer support up to this point and the ability to finance through affirm

Never seen anything delivered like this! - Mete B.Store Owner

My review is not about the mattress itself since I only had it for a day but about the way it's been delivered. I received a notification that my mattress will be delivered yesterday. I took the old mattress down and started waiting at home. It was getting late and I was wondering why it has not been delivered yet. I opened the door to check and found the box lying around by my rose bushes far from my door and one side of the was box open as if it has been thrown. They did not even knock on the door, apparently just throw it and left. Believe me, I get lots of deliveries and I've never seen anything like this. So frustrating. It made me question whether I bought my mattress from a wrong company.

Very happy - Michael L.

I am writing this review from my nest bedding mattress right now. My significant other and I are overjoyed with our decision.

The Alexander - Allen W.

This is our first memory foam mattress, to date happy with the quality. The mattress is firmer than I’m used to, but have been resting well. Maybe as it gets used it may loose some firmness but I would be okay with that. The delivery and set up went as planned no complaints.

Is the third time the charm?? - Kim Bangert

Night #1 on our new Nest bed.... Well, we've tried 3 beds so far and we may have a winner!!! Thank you Josh in the Denver Nest Store who helped me with deciding on a model. Joe Alexander- after 1 night on our Alexander Signature Soft King - my husband got up and said his back felt good and the bed was "pretty good". That is a high compliment after 3 months of rock hard "soft" beds. And after 2 failed mattresses. A suggestion: R & D should come out with a mattress for waterbed lovers. We had ours about 20-25 years and it wore out. I know I'm not the only person who loved their waterbed and is now looking for that cushiony feel but is struggling. I hope we found our new bed!!! Looking forward to night #2!!! Kim 😊👍🏼🙌🏼

Holy Grail Mattress - Stacey

I sincerely regret purchasing this mattress, because pretty much all I think about when I'm at work is getting back into bed. I recently decided that it was time for a new mattress and after inadequate research settled on a Purple. I know several people who claim, verbatim, that they are "obsessed" with their Purple, but it was entirely too firm for my liking. I realized that as a side sleeper I much prefer a softer mattress. When the recycling company came to pick the Purple up when I returned it, they told me a lot of people return them. I purchased the Nest Alexander Signature Series in soft, and I AM obsessed. It's squishy without compromising support, you sink into it but not so much that you get stuck. I do still think it has a memory foam feel to it even with the quilting, but it's not as pronounced or slow to react as many memory foams. If you're a side sleeper who loves feeling like you're sleeping on a cloud, I highly recommend the Nest Alexander Signature Series mattress in the soft comfort level.

Alexander Signature Medium - Moira H.

I love this bed! It's the best bed I have ever owned. The only bed I have ever slept on that felt better was in a fancy hotel and even though I looked under the sheets and googled the bed, it was not available for retail. I slept on my friend's bed that is the same as this, and bought mine based on that. I'm so glad I did!

BYE BYE PURPLE MATTRESS HELLO NEST BEDDING! - Maxim L.

I just got my Alexander Signature Soft Mattress and I LOVE IT!!! I've never had such an amazing mattress. When I lay on the mattress, it hugs me in all the right places and gives me support where I need it. I feel like they actually made me a custom nest for my body! I had the Purple Mattress before, and after Nest Bedding, I realize how uncomfortable the Purple Mattress was. Purple sells you a slab of rubber with holes in it and markets it as a bed. Nest sells you the Rolls Royce of mattresses with the finest materials at an affordable price. Don't fall for Purple's creative marketing. if you're looking to buy a bed, buy a real bed from Nest. If you're looking to buy a science experiment, buy a mattress from Purple. Even better, Nest customer service is AMAZING. I called in and spoke to Amber because I had some concerns with being a little warm at night, probably because of the mattress protector I was using (which I purchased from Purple) and she sent me the Nest Cooling Mattress Protector (which I'm very excited to try) FOR FREE!! You can't beat a company that cares about the products they make, and the customers that buy it. Beds are different for everybody, some people like Purple but I definitely prefer Nest Bedding. If you're looking for a Mattress give Nest a try, you'll fall in love! (and deep soothing slumber) Thank you Amber for making my sleep experience awesome! Very excited to try the cooling mattress protector!

Pretty smooth - Robert C.

Pretty smooth

The company lived up to their promise - Mike P.Store Owner

Bought the Medium mattress but it was too soft. Sent an email to the company to ask about upgrading to the firm mattress as we were within thne100 day time frame. Received a reply from the president of Nest almost immediately confirming that the new mattress would be shipped as soon as it was manufactured. It is perfect and Nest has a lifetime customer

Great for side sleepers who prefer soft mattresses - Richard J.

I had tried a Casper mattress and found it too hard, as I am a side sleeper. The purchase and shipping with Nest was easy. For the first night, I found the Alexander soft mattress to be too soft, but it took about two weeks for either the foam to firm up, or for my body to get used to it. I am now really liking the softness of the mattress, as it is plush on top and more gradiented below, while some other mattresses have a top plush layer, but you only sink until you hit a harder layer below. There was no odor with this mattress, the quilting on top is lovely and is nice enough without a mattress pad, and my dog absolutely adores the bed.

Great bed and even better company - Dennis R.

I tried 3 different beds to help my side sleep aches and pains and the nest alexander signature was the best for me. Company were great to work with.

So happy we switched. - Allison L.

We've never slept on memory foam before, so this purchase was a huge decision for us. We were coming from a 13 year old Sleep Number that couldn't be salvaged any longer. It took some getting used to for the first month, but I'm so glad we switched. No more morning back pain! Still adjusting to how it feels as a side sleeper and still healing from the joint pain the other mattress caused, but every day is better. Thank you Nest!!! I hope to buy another for our guest room one day.

NEEDS GOOD FOUNDATION - dont use bunky board!

We bought this mattress over a year ago...had no idea that they sold a separate foundation. Spent months replacing the bunky board we got from Crate and Barrell 2 times and dealing with back pain, even called the mattress mfr. The mattress mfr said they recommend their foundation instead of bunky board. Ordering it today, hopefully it will take care of the problem but paying $50 more than if I bought them together from the start. They need to update the description and recommend the foundation if they don't buy it separately OR don't even sell the mattress alone. Description said it needs a 'solid' foundation...what does that even mean? I had a hard time trying to find a bunky board that is solid wood from many retailers. Crate and Barrel's new bunky board is made of compressed cardboard! A painful process, but I like the mattress.

Works well for us

The mattress is definitely on the firm side but we both find it about right. After 11 months, the bed seems to be wearing very well... no signs of change in feel or shape. The adjustable bed is used in zero gravity every night for one of us and not used at all for the other. The adjustable bed works well for back sleepers but not side or stomach sleepers.

Six years later, we still love it!

This bed is the best we have ever slept on, even 6 years later. We have the queen, and now want a Cali king (we now have a dog sleeping with us), and will be buying another one of these latex matresses from Costco. This one will go into the guest room, and it looks brand new. It has not settled or sagged at all, even though it is used every night, by 2 people. It is NOT hot, either. The memory foam mattress we bought from Costco first, was hot, however. So we returned the memory foam and got this latex mattress. We are so happy!!!

Not so great!!

I did what i thought was plenty of research before i bought this bed.. I've waited a full year to try and get used to it, and kept telling myself and my spouse it would get better. Not only was it hard and uncomfortable but, from 3 months on, it had big depression on both sides. It seemed to get worse , not better! The only good thing is i bought it from Costco, so they agreed to take it back, no problem! Yea Costco!!

very good customer services

I bought this bed on July 7, 2016. It was my first Costco online shopping. As in warehouse shopping, the online service was very good. The delivery company did not call me to confirm the delivery time but Joshua and Carlos did great in the delivery of the bed and setting it up. Brandon at the distribution center was excellent. I could test the bed before the purchase. The latex mattress feels cool in summer compared to other types of mattresses. I hope I enjoy my bed for many years to come. I love shopping at Costco!!!

Super Comfortable; great support

I've purchased 3 of these mattress so far. The first one about 3 years ago, then another one the following year and another one a couple months ago. the first one was in a guest room and the other two were for two of my kids who loved the bed when they slept on it while visiting!

Helps with my back

I bought this bed over 2 years ago, maybe 3 years now. My husband was a reluctant buyer, because we are only early 40's :) He thought adjustable was for the nursing home. But he had enjoyed it just as much. It hasn't helped his snoring, but he enjoys the leg elevation and massage features after a tough day or workout, and elevation of his head when congested. I have had a couple of back injuries from car accidents, and sleep considerably better on this bed than ANY OTHER!! We had a memory foam before this. This is NOT memory foam. Memory foam sinks in with your weight, then when you turn over you fall back into the rut you created. Ours was also hot. This foam doesn't radiate heart back at you. I love that! It doesn't sink in. It has great support. It is nice to be able to sleep elevated without getting up in the middle of the night to prop up or go to the recliner. My bed sleeps just like it did almost 3 years ago. No sagging, indentions, or soft spots. It does creak a little when adjusting, nothing a little wd-40 can't fix. The base and massage features still work like a top. No problem! Good buy!

L-O-V-E IT!!!!!!!

Purchased and received this split King organic mattresses with adjustable bases on April 8th, 2016. What a great product! Both my husband and I absolutely love our mattresses! The adjustable bases fit perfectly inside our existing bed frame, and the mattresses are sooooo very comfortable. I have always been a side sleeper, but no more! I'm able to easily sleep on my back now. Since I am a professional singer, this is a real plus for me. Also, the adjustability allows me to (among other things) raise my head ever so slightly to allow for sinus drainage as well as legs for additional perfectly tweaked comfort. The mattress cover is soft and also feels luxurious. A 3 inch layer of softer 19 ILD natural latex perfectly compliments the firmer 32 ILD layer underneath it to softly cradle with no pressure points yet support my body superbly. Adjustable base works great. Fully articulates for customization. Zero Gravity pre programmed position is heavenly! Don't wait. Buy this now!!! You'll be glad you did! Great price and great product. Thanks Sleep Science - Well done!

Wonderful Bed!

We got this bed a couple of months ago. It is very comfortable. Unaware another person is in the same bed. Mattress is fine for us, not too firm and not too soft. No odor.

Delivery company had great personnel.

One side had a control box (located under the bed) that failed in the first few hours. Costco called the company and we had a new one installed by the company in a few days.

I would suggest going to check out Dreamfit mattress covers (they come in twin xl and their kings sheets (2 twin xl bottom sheets with one King top sheet. Their bottom sheets and mattress covers have extra elastic straps to hold the sheets in place. I found these after much research. They stay in place great. Love my bed!!

Comfortable..natural latex adjustable

The mattress delivery was great..even on time. The mattress itself is nice ...no sinking in like foam. Soft and supportive. The adjustable base is great. I do wish the lights on the remotes would come on before you try to poke the right button. Zero gravity setting is awesome!

Very comfortable

Its very comfortable. Firm for support but not too firm. My wife & I think it is the best mattress we have slept in. No smell at all.

It's SOFT, not 'medium with a bounce'

There is missing objective ILD firmness scale info in the product details. For me, 5'3 and less than 120 lb, this is surely a soft latex mattress. In general, The 'soft' designation corresponds to an ILD rating of 19-21. The ILD rating for the medium range is 24-26. After digging yourself, then you find this mattress has ILD 19 on the top 3 inch layer over another 6 inch of 32 ILD.

Terrible

I had the same mattress in queen. It was wonderful so I decided to buy the same in King and it is awful. The bigger size has no support in the middle. So the sides feels like the queen, but the middle sag tremendously and therefore gives no support at all. After 2 years of back pain, I have finally enough money to buy a different one. This was so disappointing because I still have the queen and still love it.

Sleep Science Queen, 2019

For a mattress that is above the norm; The 10" pad is very supportive of a 260lb man. A Very dreamy firmness and this mattress is easy to lift the corners during making your sheet fit well. The overall weight is about -85-88-lbs, and ladies are able to shift the full mattress with easy. Upon receiving the purchase, the unit did not smell of any odd chemical fumes, and We just enjoy the best sleep and naps of our Year. . . . The value in a modern mattress is a good investment, and the quality will provide a good 15 years span to your resting world.

Was Ok but then 4 Years Later

This was great at first. It was very firm which we loved. It slept a bit hot but we made adjustments and got a wool topper. But now 4 years later-I am waking up throughout the night with shoulder and hip pain. After some reading I find that memory foam can 'soften' and lose support. I am so annoyed that after 4 years my mattress is failing.

I bought this Mattress 2 weeks ago...

I bought this Mattress 2 weeks ago, it came on time but the mattress is not inflated to 10 inches. The cover is still have baggy and feel like missing layers

good value, but edges too soft

Bought this model from Costco a few years back. One big reason I chose this one was the design included firm(er) foam edges (that you can't feel), but they help the edges not just compress to nothing when you sit on the them - and it really works. Fast forward to last month, bought another of same model for guest room. While new cover is nicer, mattress is a little softer and... no more firm sides. ;( Yes, the description shows a drawing that shows it still has foam wedges along the edge, but the design has changed so they look smaller, and are definitely not effective. Sides compress down to almost unsittable level. Returned and will replace with (sadly) one that has more robust edge support. Guess Sleep Science figured out what the 'money' feature really was.

Great!

After years of suffering from a traditional mattress, I was ready to make a switch. It took a few weeks to get used to, but I'm so glad I bought this mattress. It is very comfortable!!

Worst mattress ever!

I bought this mattress a little over 2 years ago and it is the worst I've ever slept on. I have had back issues ever since, and thought it was due to the fact that I picked up playing golf right around the same time. After traveling for work over the past year and a half, I realized my back is always fine as long as I'm not sleeping in my own bed. A friend just told me Costco would take it back so I will be returning it ASAP.

Uneven

I’ve been using this mattress for about 7 weeks. It seems to have a ridge in the middle, and it feels uneven to me. This is our third 10-inch Sleep Science mattress, and the first to feel uneven.

Fantastic SLEEP

We have 3 Sleep Science mattresses now and love them. We sleep so sound and deep. We feel great in the morning

Our backs are thanking you, Sleep Science

We've been sleeping, and I do mean sleeping, on this mattress for six weeks now. I was in physical therapy for my back when the therapist asked me, "Could it be you need a new mattress?" I came home, looked at our Sleep by Number and decided we did.

On the firmer side, but love it

We purchased this bed over 6 months ago and I waited to do my review to see how it lasted over time. It was a bit firm for me (a side sleeper) but my husband liked it. We purchased a three inch foam topper a few weeks later and it really helped with my shoulder comfort. Between the topper and the mattress, I sleep so well!! We are very happy with our purchase, would recommend for someone who likes a firmer mattress.

BEST Night's Sleep

We purchased this for my 6'5" son in college because he had the 3rd floor loft up a spiral staircase and we could not get anything up the stairs. This mattress comes condensed, in a box. We had no idea what a great mattress it was until we visited and stayed in his room and could sleep through all the FSU football weekend noise! Since then, we purchased mattresses for our two daughters and two more for our beach vacation rental condo. We have had 3 couples so far that rented our condo and actually ORDERED the mattress while they were still staying in the condo so that it would arrive at their house before they returned. That should tell you how good this mattress feels. It's firm, but not too firm. It gives great support. If this mattress only lasts 10 years, for the price, and the quality sleep we get, it's priceless! Come stay at our direct ocean, corner condo and try it out while you enjoy a New Smyrna Beach, Florida ....call it a "research trip"!

Great mattress and great customer service!

I ordered this mattress from Costco and before I had even received it, I had a letter from the company to thank me for the purchase and contact information should I have questions or problems with the mattress. I have been using now for a week and really like it. I am a side sleeper and this is perfect for me. I would not hesitate to order another when I need one!

Very comfortable, great price and it didn't smell

This was the second Sleep Science 10" foam mattress we've bought and it is even better than the first one. (Usually memory foam mattresses outgas for a few days after being unpacked, but there was zero odor this time.) We bought it for our guest bedroom and we still have the six years old mattress in our master bedroom. The Sleep Science memory foam mattresses are the best value in memory foam for price and performance over several years. We miss our mattress dearly whenever we travel and sleep on hotel/motel beds. We are 100% satisfied with these Sleep Science memory foam mattresses and recommend them to everyone!

My guests love it

Had guests in for 10 days and they were delighted to have such a comfortable mattress to rest on while on vacation. The mattress was reported to "hug" their bodies and it appeared to have great recoil to it's original state after being vacated for a few minutes. Would suggest it for a guest room.

Great bed for our guest room.

We bought this bed for our guest room, because we enjoyed the bed we had bought 2 years ago for our own bedroom. Sleep Science had a great mattress. Thank you Costco!

great mattress

hypo allergy , firm mattress exactly the that I want , at same time soft enough to give me excellent sleep .

To soft

I already returned to costco. It is listed under firm and it was very soft and spongy. Its great if you like a very soft mattress

Exceeds expectations

I knew I would get good quality beds at Costco. We bought queen plush & wanted 2nd bed to be firm. Very happy.

GOOD BUT CAVEAT

Early indications are this Sleep Science mattress is a good product. However, there is an important CAVEAT: Sleep Science memory foam mattresses must be supported with a solid base. I purchased a platform bed from Costco with the mattress. The bed had slats as support. I was told by a Sleep Science Rep that I would need a 1/2 inch thick piece of plywood to properly support the mattress. I had two bad choices: 1. Try to (re)box a 78 pound bed and return to Costco. 2. Buy the plywood, have it cut to fit, and, somehow get it home. I chose the plywood. What a hassle. While I recommend the Sleep Science mattress, I caution not to buy platform bed with slats to support it.

Too hard!

Bought this Queen Sleep Science from Costco in June 2015 for a summer home. Read all the reviews and thought it would work but it's just too, too hard. Cheaper guest bedroom mattress is more comfortable! Awake with pain every morning. Finally added a memory foam topper last year to make it bearable, but we're replacing it now - Year 3 (total sleep time slightly more than 12 months!).

A little dissapointed

Despite waiting a over a month, the corners of the mattress never filled out to be fully 'square'. Instead they round off and don't fill the mattress cover completely.

Son LOVES this bed

Even more than a year after ordering, our son still comments on how he loves this bed.

Very comfortable

We weren't sure buying a bed online & in a box would work out for us, but we have been very happy with our new mattress. At first, it feels really firm, but then it gives way so that hips, shoulders, etc are cradled. I am amazed at how light the mattress is, too. When making the bed, it's super light when picking up the corners to tuck in the bottom sheet. I thought it would be really heavy, like other memory foam mattresses. Overall, we're very happy with our purchase.

My back feels good!

The bed is the perfect firmness for my back. I am able to wake up without pain. Costco shopped it very quickly! Thank you!

Poor quality, sagging/sinking in just a year

I bought this mattress 5 years ago. I researched extensively to find a firm mattress and based on good review I bought this. People shouldn't review any mattress until they use it for at least a year. Many reviews here written are just after a week or few weeks. Most of the mattresses would feel nice when new. The real test starts after a year. We loved this mattress in the beginning. Perfect amount of firmness, edge support, no hot flashes etc. After a year it started to sag n sink. We're not even large people I was 135lbs and my husband was 160 lbs. I started to wake up feeling really hot and back started to hurt. In just 2 years this mattress was really uncomfortable and some how we tried to manage it with some toppers but nothing worked. Edge support is gone, foam is of very poor quality. It has actually caused me severe back pain. I do not recommend this mattress. This is the first product from costco that I really really hate.

Worse mattress ever

We bought this mattress thinking it’s firm . Backache started after first sleep on it. Called Costco to return. Costco return good , mattress bad bad.

No bone pain with this mattress!

This is my third Sleep Science Mattress. 1st was a 13” Queen which I gave to friends after I had it 10years. I had to downsize. They still say it is the best mattress they have ever slept on. The 2nd was a twin which was better than other conventional mattresses but I went on to this 10” full size to get back the 3” wedge support all around and it is a much better mattress. I suffer from bone pain and with this mattress I do not have it. The only Con to these mattresses is that they are warm so if you live in a hot climate consider that. If you live where it is cold it will make it an extra plus. I will buy another when this one wears out which I don’t anticipate happening any time soon.
